Power and data cables are used by building services engineers and electrical contractors to create a network of services throughout a building. Data cabling can be used to automate building services through a building management system (BMS), such as heating, ventilation, air conditioning (HVAC) and security appliances. For industrial

Enclosures, housings and cabinets are used for storing or protecting electrical equipment or industrial machinery. Smaller units provide secure storage and protection from the elements for equipment such as meters and electrical switchgear. Larger enclosures are used for plant such as pumps or large instruments. Steel is a common material for

Radiators work as part of central heating or local room heating systems. Different heat outputs, wattages and IP ratings suit them to particular applications in domestic, commercial and public buildings. Sculptural radiators are design features in their own right. Their distinctive geometric shapes and high-quality stainless steel finishes make

HVACR controls allow building owners and occupiers to tailor environmental conditions to their users' precise requirements. A good control system will be easy to use and install, ensure consistent operation of heating, air conditioning, ventilation and refrigeration equipment, and minimise energy consumption. Some systems allow central control of

In an effort to prevent environmental pollution and damage to human health, legal requirements now dictate that hazardous chemicals are kept in secure chemical stores . The government advises that chemical storage areas are secure, away from heavy machinery and vehicles to prevent accidental damage, unlikely to flood, and clearly signposted. The

Radiant heaters are used to heat buildings where a convection heater , such as radiators or trench heating, would not be suitable. They are typically specified for large areas such as sports halls, industrial buildings, warehouses, churches and atria. Energy emitted from a warm element directly heats people and objects rather than the air as with

Flush controls for suitable use with WCs or urinals in public toilets. Push buttons / pads are a discreet alternative to traditional lever handles and are available with a water-saving, dual flush mechanism. Hands-free sensors, proximity controls and timer-based controls use infrared technology, which prevents the transmission of harmful bacteria

Grease traps and separators remove fats, oil and grease (FOG) from grey water. They are installed in restaurants, fast food outlets and other commercial kitchens to prevent drainage pipes from becoming blocked. Grease settles at the bottom of the trap, from where, depending on the system, it is either removed by hand or consumed by

Chilled beams and ceilings are a type of convection HVAC system suitable for use in large buildings. They can provide both heating and cooling. Passive chilled beams rely solely on convection, while the active type , also known as induction diffusers, are connected to ducts to push supply air to the unit, increasing the heating and cooling

Ventilation fans are designed for air supply, air extract or air supply and extract functions. Models are available for a host of applications in the residential, commercial (including IT and telecomms), and industrial sectors. They can be ceiling, duct, roof, wall or floor mounted. Different types include: - Centrifugal fans , which feature a fan

Packaged pumping stations are installed where the gravity drainage of surface water, wastewater or sewage is not possible. They 'lift' the liquid concerned to the requisite height, either into the drains or a septic tank. For this reason they are also known as lifting stations. Pumping stations typically consist of one or more submersible pumps

Packaged plant rooms are self-contained prefabricated enclosures that house HVAC, power or communications equipment in a single centralised facility. Mechanical and electrical services are integrated into a single containerised or skid-mounted unit, which is manufactured offsite. It is then delivered fully assembled, or in kit form for sites with

Drainage and sump pumps are used to empty flooded basements, septic tanks, swimming pools, drainage pits and containers, and to drain and dewater building sites, commercial areas, gardens, gullies and pedestrian underpasses. Fixed or portable units for internal or external use are available for moving clean water, grey water, rainwater, surface

Humidifiers are used to improve dry indoor air conditions that can be created by air conditioning or heating systems. Some provide humidification only , while others offer both cooling and humidification . Isothermal humidifiers use a variety of methods to heat the water to create steam, and require an energy source. Immersed electrode humidifiers

Boilers provide hot water or steam for general domestic use, central heating systems and industrial processes. Boilers for domestic / residential central heating and hot water are compact units, designed to fit into small spaces in the home. Condensing and combi boilers are typically specified for these applications. Boilers for commercial
